Resumo
Atualmente , a cefalometria passa po questionamentos com relação a sua precisão em avaliar o grau e a localizaçãoda deformidade a ser tratada. a abtenção das radiografias cefalométricas, de forma padronizada, pela metodologia da postura natural de cabeça(PNC) tem pouca popularidade no Brasil, talvez pelos poucos estudos existentes sobre o tema. Sendo assim, o objetivo no presente estudo foi verificar se havia diferença nos valores da análise cefalométrica do perfil tegumentar, tendo como base a Análise facial de Arnett, realizada em radiografias cefalométricas em norma lateral, digitalizadas, obtidas pelas técnicas convencional e me PCN. àra tal propósito 100 radiografias cefalométricas, pertencentes ao arquivo digital da disciplina de radiologia da Faculdade de odontologia de São José dos Campos da Universidade Estadual Paulista Julio de Mesquita Filho - UNESP foram utilizadas e as medidas foram realizadas duas vezes com um intervalo de 15 dias entre elas. Não encontramos significâncias entre os dias. Utilizamos o teste ANOVA para comparar o resultado médio entre os sexos para cada uma das linhas e concluimos que não houve diferença média estatisticamente significante entre os sexos. Fizemos também uso do T-Student Pareado para comparar os resultados entre as linhas LVV e perp PHF para todos os parâmetros. Concluímos que houve diferença média estatisticamente significante entre as duas metodologias estudadas, e assim não devemos substituar a linha LVV pela linha perp PHF.
Currenty , the cephalometry passes for questionings with regard to its precision in evaluating the degree and the localization of the deformity to be treted . The obtainment of the cephalometric lateral x-rays, of standardized form, for the methodology of the natural head posture has little popularuty in Brazil, perhaps for the few studies on the theme. Being thus, the aim in the present study was verif IF it hás difference in the on Arnett's facial analysis, carried through in digitalizided cephalometrics x-rays gotten by the conventional and with natural head posture techniques, For such a purpose 100 cefalomretic X-rays, pertaining to the digital archive of the discipline of Radiology of the Faculty of Dentistry of Saint José of the Fields of the State University of São Paulo Julio de Mesquita Filho UNESP went used and the measures were carried out two times with an interval of 15 days between them. We do not find significations between the days. we use the test ANOVA to compare the middle result between the sexs for each one ofthe lines and end that there was no statistically significant middle difference between the sexs. We did also use of the T-Student Pareado in order that LVV compared the results between the lines and perp PHF for all the parameters. It was concluded that there was statiscally significant middle difference between both methods studied, so we should not switch the LVV line for perp PHF line.
